Document Title Trial

Vignettes are long form documentation commonly included in packages. Because they are part of the distribution of the package, they need to be as compact as possible. The html_vignette output type provides a custom style sheet (and tweaks some options) to ensure that the resulting html is as small as possible. The html_vignette format:

Vignette Info

Note the various macros within the vignette section of the metadata block above. These are required in order to instruct R how to build the vignette. Note that you should change the title field and the \VignetteIndexEntry to match the title of your vignette.

Styles

The html_vignette template includes a basic CSS theme. To override this theme you can specify your own CSS in the document metadata as follows:

output: 
  rmarkdown::html_vignette:
    css: mystyles.css

Figures

The figure sizes have been customised so that you can easily put two images side-by-side.

ggplot2 Example

dt <- as.data.table(mtcars)

dt[, cyl := as.factor(cyl)] %>% 
    ggplot(
        aes(
           x = hp,
           y = mpg,
           color = cyl)) + 
    geom_point() +
        theme_innteam() + 
            scale_color_brewer(type = 'qual', palette = 6) +
                 labs(title = 'Another mtcars Plot',
                      subtitle = 'But this time it is a data.table',
                      caption = 'The theme is coherent with the overall theme in the package')

Plotly Example

dt %>%
  plot_ly(x = ~hp,
          y = ~mpg,
          color = ~cyl,
          type = "scatter") %>% 
    plotly_innteam(plot_title = 'This is my title',
                     plot_subtitle = 'Here we will see a subtitle',
                     plot_caption = 'Source: innteamUtils package',
                   plot_xaxis = 'LifeExp',
                   plot_yaxis = 'Population',
                     width = 900, height = 500)

You can enable figure captions by fig_caption: yes in YAML:

output:
  rmarkdown::html_vignette:
    fig_caption: yes

Then you can use the chunk option fig.cap = "Your figure caption." in knitr.

More Examples

You can write math expressions, e.g. Y = Xβ + ϵ, footnotes1, and tables, e.g. using reactable().

reactable(iris, highlight = TRUE, filterable = TRUE, resizable = TRUE, wrap = FALSE)

Also a quote using >:

“He who gives up [code] safety for [code] speed deserves neither.” (via)

x <- seq(1:5)
x
[1] 1 2 3 4 5
